'They can have different nutrition, different levels of hormones.'Dr Rieger says he won't be have research into stereotypically gendered behaviour hampered by the controversy people attach to it.'To me it’s just one way of assessing behaviours — that is a better method than asking people,' he said. It’s very dangerous to start going down the route of thinking that way.'Another 30-year-old pair, who wished to remain anonymous, hope their involvement in the study helps answer questions they have asked for years.
'I was always fascinated with it,' one of the twins said. 'How can it be that one egg split and in such a large factor of our life we were programmed so different? She was very into make-up.'Their music interests also clashed, with one preferring Jimi Hendrix while her sister listened to boy bands.
'A lot of people jump to the conclusion it must be genetics.' Scientists have established a genetic component to sexuality, but they have also claimed that is not the whole story.
And given this study's twins share the same genetics, that component can’t be the whole story in these cases, with Dr Rieger looking to environmental factors.'This shows there is something early on, in the early environment, that has nothing to do with genes but can still have a tremendous effect on sexual orientation,' he said.
Now they and 55 other twin pairs are at the centre of a study by University of Essex researchers.
In the past, scientists have searched for signs of how sexuality manifests before puberty, such as gender-atypical mannerisms of behaviour.

progressive attitudes; (b) Multiple ways of perceiving sexuality: Constructing a sexual identity along the life course; and (c) Sexual self-perception: Integrating late life and widowhood.
Interest in sexuality intensifies during the onset of puberty, and sexuality is often a vital aspect of teenagers' lives.
In humans, sexual interest may be expressed in a number of ways, such as flirting, kissing, masturbation, or having sex with a partner.
The origins of their differing sexual identities were studied in an effort to find out when and how sexuality develops in childhood.
Sarah remembers how Rosie's tomboy tendencies provided an insight when they were growing up, telling The Times her boyfriends 'instantly felt more at home' with her sister.'She liked football, talked about boy things, played video games,' she said. I’m going to go and play with Rosie." 'I’d get jealous that they liked her better.'But Sarah soon realised that her sister just wasn't as interested as her in the company of boys.'When they tried to get romantic with Rosie she’d say, "That’s not me." Then they came back,' she explained.
The research also ruled out parenting as far as is possible to do so, because all the twins studied shared the same home.
